Works fine for me. Please try if you can reproduce it or if it works fine

1.in safe mode.

2.or by creating a new profile

@Srinivas, sorry for the delay. I still see this using either safe mode or a new profile. Here is a terminal output...

NOTE: child process received `Goodbye', closing down

The last line is what I see when I exit Firefox, but I still have to kill Firefox via terminal or task manager.

After filing this bug I installed Iceweasel 4 beta9 and have had no problems. I also asked for confirmation at the nightly builds thread @ forums.mozillazine.org but received none, though they have very few Linux testers there these days. I'd say go ahead and close this bug, but it certainly is odd that this happens every single time Firefox calls gecko-mediaplayer on my brand new aptosid (Debian sid) install.

Iceweasel may be looking in different places for plugins.
Is it still using gecko-mediaplayer?

Comment 4

[hhh]

@Karl, yes, but your suggestion solved my problem. Running Iceweasel from a terminal showed errors about missing child process mencoder. I installed mencoder and libtwolame0 and Firefox shuts down properly now. Sorry for not checking terminal outputs in the first place, I'm way out of practice in bug reporting and troubleshooting.

OK, thanks.  I'll mark this WORKSFORME.
